DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

This disclosure is further described in combination with drawings and specific embodiments.

Example

Referring to FIG. 1 to FIG. 6, an assembled Christmas tree may include a plurality of trunk units 1 that can be assembled, and the trunk units 1 are hollow tubular body. When two adjacent trunk units 1 are connected, the low end of the tubular body of the trunk unit 1 located above is coupled with the upper end of the tubular body of the trunk unit 1 located below.

The Christmas tree can further include: a power connector 2, including the female end connecting portion 21 and the male end connecting portion 22, which are arranged at both ends of the tubular body respectively. The female end connecting portion 21 is electrically connected with the male end connecting portion 22. When the two adjacent trunk units 1 are connected, the male end connecting portion 22 of the power connector 2 of one trunk unit 1 is electrically connected with the female end connecting portion 21 of the power connector 2 of another trunk unit 1.

The Christmas tree can further include a power port 4. The surface of the trunk unit 1 is provided with a mounting hole, and the power port 4 is embedded in the mounting hole. The power port 4 is electrically connected with the corresponding power connector 2.

In the technical solutions, the power connector 2 is arranged in the tubular body. When the trunk is assembled, its interior power connector 2 is also connected; besides, the power port 4 is provided at the trunk side, which can provide power supply for lamps on the corresponding branches. When a lain fails, the line can be directly cut off. It is easy to replace and maintain. The female end connecting portion 21 and the male end connecting portion 22 of the power connector 2 can be integrated as a whole, or can be separated to form two single units.

Further, the female end connecting portion 21 includes a plug hole 212, which is equipped with two electrodes 211 arranged separately; the male end connecting portion 22 includes two concentrically arranged connecting terminals 221 which are coupled to each other with an insulating layer between them. When the two adjacent trunks 1 are connected, the two connecting terminals 221 of the male end connecting portion 22 of the power connector 2 of one trunk unit 1 are abutted against the two electrodes 211 at the female end connecting portion 21 of the power connector 2 of another trunk unit 1 respectively.

When a single hole plug mode is used, the female end connecting portion 21, and the male end connecting portion 22 are arranged at the axis of the trunk unit 1. Therefore, when two trunk units 1 are connected, they can rotate relative to each other, without affecting the direction of the current of the lines and it is easy to adjust. This connection way is usually used in low voltage decorative lamps; the voltage between two electrodes 211 is low, which will not produce electric arcs.

Further, the female end connecting portion 21 may include two plug holes 212, which are equipped with an electrode 211 respectively; the male end connecting portion 22 includes two connecting terminals 221. When the two adjacent trunk units 1 are connected, the two connecting terminals 221 of the male end connecting portion 22 of the power connector 2 of the trunk unit 1 are abutted against the two electrodes 221 at the female end connecting portion 21 of the power connector 2 of another trunk unit 1 respectively.

The two connecting terminals 221 are connected to the two electrodes 211 respectively, thus ensuring a secure line connection. This connection way can be used in all decorative lamps without producing arc or leakage caused by high voltage between two electrodes.

Further, a periphery of the power port 4 is provided with an annular protector 3, and two opposite sides of the power port 4 are equipped with a clamp 41 respectively. An outside of the power port 4 is provided with a flange 42, where one end of the protector 3 is abutted against the flange 42, and the other end of the protector 3 is provided with a supporting leg 31 abutted against the clamp 41. An outer end face of the supporting leg 31 is provided with an undercut 32.

At present, when the power port 4 is mounted, one end is connected with the power connector 2 via wires and then inserted to the mounting hole 12 of the trunk unit 1, and its flange 42 is located outside of the mounting hole and fixedly connected with the trunk unit 1. When the protector 3 is used and the power port 4 is inserted to the mounting hole, the undercut 32 of the protector 3 is squeezed into the mounting hole and clamped with the trunk unit 1, and the undercut 32 and the flange 42 are located at two sides of the mounting hole respectively, to achieve the clamping effect, which can avoid the use of connecting pieces for fixture and be easy to install.

Further, when the two adjacent trunk units 1 are connected, the lower end of the truck unit 1 located above is coupled to the upper end of the trunk unit 1 located below, and the upper end of the trunk unit 1 is provided with a fixed ring.

When coupled together, the lower end of the trunk unit 1 often collides with the upper end of another trunk unit 1. After a long time of collision, it will affect its deformation. To avoid such circumstance and extend the service life, a fixed ring is provided at the upper end part.

Further, the lower end surface of the trunk unit 1 is provided with a guide block 12, and the upper end surface of the trunk unit 1 is provided with a guide groove 11 matching with the guide block 12.

When two connecting terminals 221 are used in the male end connecting portion 22, the two adjacent trunk units 1 should be coupled at a certain angle. The setting of the guide block 12 and the guide groove 11 makes assembly easier.

The disclosure has been described in detail. Technicians skilled in the art should know that the technical solutions can be modified or substituted equivalently without departing from the spirit and scope of them.
